ORA-00001:违反了唯一约束主键 [英] ORA-00001: unique constraint primary key violated

问题描述

DELETE from dbo.T_LIAV_AGENT_STATE_APPROVAL SAP
WHERE EXISTS (SELECT UNIQUE 1 FROM MCS_SYNC_STATE_APPR APP

                inner join MCS_SYNC_NAME SN on SN.SE_NAME_ID = APP.SE_NAME_ID
                                    and SN.ACTION in('U','S')
                Where APP.SE_name_id = SAP.AV_NAME_ID
                and APP.SYNC_INSTANCE_ID = param_inst_ID);
COMMIT;

INSERT INTO dbo.T_LIAV_AGENT_STATE_APPROVAL

SELECT  UNIQUE 

    APP.SE_NAME_ID            AS AV_NAME_ID,
    APP.STATE                 AS AV_STATE,
    APP.APPROVAL_TYPE         AS AV_APPROVAL_TYPE,
    APP.START_DATE            AS AV_START_DATE,
    APP.END_DATE              AS AV_END_DATE,
    APP.APPOINTED             AS AV_APPOINTED,
    APP.RENEWAL_DATE          AS AV_RENEWAL_DATE,
    APP.LICENSE               AS AV_LICENSE,
    COMPANY_NAME_ID           as AV_COMPANY_CODE,
    SYSDATE                   AS TSTAMP,
    SYNC_USER_NAME_ID         AS AV_FIRST_USER_ID,
    SYSDATE                   AS AV_FIRST_DATE,
    NULL                      AS AV_LAST_USER_ID,
    NULL                      AS AV_LAST_DATE

FROM MCS_SYNC_STATE_APPR APP

WHERE exists (select 1 from t_liag_agent AG
                     where AG.ag_name_id = APP.SE_NAME_ID)
and APP.SYNC_INSTANCE_ID = param_inst_ID;

这是SQL部分，调试代码时出现错误:

Here is the SQL part and I am getting error when I debug the code:

ORA-00001:在T_LIAV_AGENT_STATE_APPROVAL ...处违反了唯一约束主键...

ORA-00001: unique constraint primary key violated At T_LIAV_AGENT_STATE_APPROVAL...

，这是主键约束依赖于AV_NAME_ID, AV_STATE的2列.

and these are the 2 columns which the primary key constraint relies on AV_NAME_ID, AV_STATE ..

我没有重复的数据...您认为还有其他原因吗?

There is no duplicate data as per me ...Do you think any other reason?

推荐答案

Select语句缺少一列，因此出现此错误.当我将该列添加到select语句中时，它运行良好.

Select statement was missing a column when compared to Insert table statement so there was this error. When i added that column to the select statement it worked perfectly.
